    Unified Incremental Multimodal Interface for Human-Robot Interaction2011Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Face-to-face human communication is a multimodal and incremental process. Humans employ  different information channels (modalities) for their communication. Since some of these modalities are more error-prone to specic type of data, a multimodal communication can benefit from strengths of each modality and therefore reduce ambiguities during the interaction. Such interfaces can be applied to intelligent robots who operate in close relation with humans. With this approach, robots can communicate with their human colleagues in the same way they communicate with each other, thus leading to an easier and more robust human-robot interaction (HRI).In this work we suggest a new method for implementing multimodal interfaces in HRI domain and present the method employed on an industrial robot. We show that operating the system is made easier by using this interface.

    Visionary Expectations and Novice Designers: Prototyping in Design Education2017Inngår i: Design and Technology Education: An International Journal, ISSN 1360-1431, E-ISSN 2040-8633, Vol. 22, nr 1, s. 1-16Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In information design education, we strive to find methods that provide students with opportunities to explore different ways of learning and designing. We seek to support development of contextual competences that will be helpful in navigating an unknown future of design in society. A challenge in today's design education is to formulate and use methods that support design students in developing competencies in the space between basic form training and context-rich training. The aim of this study was to evaluate prototyping exercises in design education where the focus was in that in-between space. The study is based on 33 prototyping workshops done between 2008 and 2015 and involving 160 students and two design teachers. Four different approaches to prototyping exercises are described, examined and evaluated: "spatial prototyping," "multi-material prototyping," "physical prototyping," and a mix between the latter two, "physical multi-material prototyping." The results show that the prototyping exercises did support the learning of diverse competencies in the in-between space of basic form training and context training. However, the exercises were also counterproductive and met with different kinds of resistance. The results of the study invite to a dialogue on how different prototyping techniques can stimulate learning in relation to future design competences.

    Climate-smart information design: Visualizing residential electricity use over the Internet2011Inngår i: Information Design Journal, ISSN 0142-5471, E-ISSN 1569-979X, Vol. 19, nr 1, s. 3-17Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In light of global warming, energy conservation is indispensable. Residential electricity use, nevertheless, escapes consumers’ notice. Thus feedback is essential, yet households’ access to information is vastly limited. Smart metering renders continuous feedback over the Internet possible, but users perceive existing web tools to be inaccessible and incomprehensible. Hence the aim has been to design a user interface so as to serve the purpose of increasing awareness and energy efficiency in households. Ease of access and straightforwardness have been established as key factors and conventional bar charts in combination with color symbolism have proven to be useful in this respect.

    Togetherness and Respect - Ethical Concerns of Privacy in Global Web Societies2006Inngår i: AI & Society, ISSN 0951-5666, Vol. 20, nr 3, s. 372-383Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Today's computer network technologies are sociologically founded on hunter-gatherer principles; common users may be possible subjects ofsurveillance and sophisticated internet-based attacks are almost impossible to prevent. At the same time, information and communication technology, ICT offers the technical possibility of embedded privacy protection. Making technology legitimate by design is a part of the intentional design for democracy. This means incorporating options for socially acceptable behaviour in technical systems, and making the basic principles ofprivacy protection, rights and responsibilities, transparent to the user. The current global e-polis already has, by means of different technologies, de facto built-in policies that define the level of user-privacy protection. That which remains is to make their ethical implications explicit and understandable to citizens of the global village through interdisciplinary disclosive ethical methods, and to make them correspond to the highethical norms that support trust, the essential precondition of any socialization. The good news is that research along these lines is already inprogress. Hopefully, this will result in a future standard approach to the privacy of network communications.

    Interface Design for Decision Support Systems: A Case Study of a Sales Performance Management Tool2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    In this thesis a case study is presented, which explored what structural and visual aspects of a sales performance management tool's user interface that generated most recurrent problems for novice users. The purpose of the case study was to investigate if identified problems related to structural and visual aspects could help improve the current user interface of the sales performance management tool. In order to investigate these objectives was evaluation research conducted, this in the form of five direct user observations, which adopted the think aloud protocol. Qualitative data obtained from the observational study were analyzed using thematic analysis, which helped identify recurring themes within the data. The results from the case study indicate that it is possible to reveal structural and visual problems within a user interface with novice users, this through using the direct observation technique with the think aloud protocol. Problems identified in the observational study showed to be rather superficial, which indicate that evaluating a user interface with novice users has its limitations. Evident from the case study was that all novice users either found or encountered some problems related to structural and visual aspects. Moreover, the results from the case study indicates that evaluating a user interface with novice users can help improve a system's user interface. However, the improvements are likely to be incremental and not radical.

    Towards a Multi-OS Architecture for Consistent User Interface Experience2016Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Vehicles have greatly changed over the last decades. Originally, they were used as a means of transportation, and their drivers were solely engaged in the driving task. In modern cars the user, i.e. the former driver, has to interact with many different systems, which provide access to different domains, such as vehicle functions (monitoring speed, fuel consumption), safety related features, comfort and infotainment. Advancements in technologies make it possible to cope with the increasing amount of features, as for example the introduction of input and output modalities that allow new ways of interaction, such as touch(-screens), voice control or gesture recognition. In the end a user has to interact with all systems through the overall user-interface. This requires a high usability and a consistent look and feel in order to provide a consistent user experience.

    On the technology side, developers have to cope with rising complexity, dependencies and inter-connections of about 80 different embedded systems in a premium car. The introduction of multi-core systems opened the way for new approaches, like Multi-OS environments. There multiple operating systems are consolidated onto a single hardware platform by the use of hardware/software virtualization. This allows for example to run real-time operating systems (RTOS) for safety critical cluster applications next to a general purpose operating system (GPOS) for infotainment applications. This also poses new challenges, such as the contradiction between a clear separation meant to reduce complexity, dependencies and to mitigate the risk of interferences, and interconnections that are required to create a composited user-interface.

    In this thesis, the challenges of compositing heterogeneous systems in an automotive context are explored. Current approaches are studied and the contradiction of separation and interconnection is explained. Based on this, concepts are introduced and software architectures are proposed, which can be used to implement composited user interfaces for Multi-OS environments. Furthermore, an application prototype that is used to verify the proposed software architecture in regard of graphical user-interfaces, called HTML-UI-Compositor, has been implemented. The HTML-UI-Compositor also provides a simple way of compositing graphical user-interfaces through the adaptation of a web browser engine, which allows well-known standard web development tools and languages to be used to create composited user-interfaces. Those are the first steps towards a Multi-OS architecture that supports a consistent user interface experience.

    Towards an architecture for an UI-Compositor for Multi-OS environments2016Inngår i: Software Architecture: 10th European Conference, ECSA 2016, Copenhagen, Denmark, November 28 - December 2, 2016. Proceedings, 2016, s. 138-147Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Separation through hardware/software virtualization on operating system (OS) layer reduces complexity in automotive software. Automotive software is categorized into domains (e.g. comfort, safety related features, driver assistance) and each domain is handled by a separate OS, which contains domain-specific applications. A common user interface (UI) for all applications from all domains is created through an UI-Compositor, which composites and manages the different input/output modalities.

    While interactions with a single OS with multiple applications and input/output modalities are well known, we find that a composition of applications from different OSs or a composition of multiple OSs into a single UI is challenging. In this paper we investigate architectural patterns for an UI-Compositor for Multi-OS environments and suggest a new architecture that supports the concept of separation.

    Head-mounted Projection Display to Support and Improve Motion Capture Acting2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Current and future animations seek for realistic motions to create an illusion of authentic and believable animations. A technology widely used to support this process is motion capture. Therefore, motion capture actors are used to enrich the movements of digital avatars with suitable and believable motions and emotions.

    Acting for motion capture, as it is performed today, is a challenging work environment for actors and directors. Short preparation times, minimalistic scenery, limited information about characters and the performance as well as memorizing movements and spatial positions requires actors who are trained and able to highly rely on their acting and imagination skills. In many cases these circumstances can lead to performances with unnatural motions such as stiff looking and emotionless movements, as well as less believable characters. To compensate this, time-consuming repetitions of performances or post-processing of motion capture recordings is needed.

    To improve this, we explore the possibilities of acting support and immersion through an interactive system supporting motion capture actors during their performances. In this process, we use an approach that combines research methods from interaction design and computer science. For our research, we firstly identify the challenges actors are facing in motion capture, as well as suggest possible concepts to support the actors. Thereafter, we explore initial prototypes built to support actors during their performance in a motion capture studio. The resulting insights from these initial prototypes led to the design exploration and development of a mixed reality head-mounted projection display that allows showing virtual scenery to the actors and provides real-time acting support. Thereafter, we describe our developed mixed reality application and our findings on how hardware and software prototypes can be designed as acting support, usable in a motion capture environment. A working prototype allowing to evaluate actors' experiences and performances was built as a proof-of-concept.

    Additionally, we explored the possibility to use our developed mixed reality prototype in other fields and investigated its applicability for computer games and as an industrial simulator application.

    Finally, we conducted user studies with traditionally trained theatre and TV actors, experienced motion capture actors and experts, evaluating the experiences with our prototype. The results of these user studies indicate that our application makes it easier for motion capture actors to get into demanded moods and to understand the acting scenario. Furthermore, we show a prototype that complies with the requirements of a motion capture environment, that has the potential to improve motion capture acting results and supports actors with their performances.

    Supporting motion capture acting through a mixed reality application2018Bok (Annet vitenskapelig)
    Abstract [en]

    Current and future animations seek for more human-like motions to create believable animations for computer games, animated movies and commercial spots. A technology widely used technology is motion capture to capture actors’ movements which enrich digital avatars motions and emotions. However, a motion capture environment poses challenges to actors such as short preparation times and the need to highly rely on their acting and imagination skills. To support these actors, we developed a mixed reality application that allows showing digital environments while performing and being able to see the real and virtual world. We tested our prototype with 6 traditionally trained theatre and TV actors. As a result, the actors indicated that our application supported them getting into the demanded acting moods with less unrequired emotions. The acting scenario was also better understood with less need of explanation than when just discussing the scenario, as commonly done in theatre acting.

    Evaluation of a Mixed Reality Projection Display to Support Motion Capture Acting2016Inngår i: 13th EAI International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present an evaluation of our mixed reality prototype for motion capture acting, tested with experienced motion capture actors. Motion capture acting requires trained and experienced actors who can highly rely on their acting and imagination skills. This is especially the case when preparation times are short and scenery needs to be imagined. To support actors in such cases, we developed a mixed reality application that allows showing digital scenery and triggering emotions while performing. In this paper we tested our prototype with experienced motion capture actors performing short acting scenes. We also evaluated the prototype’s usefulness for motion capture with four actors and four motion capture experts. The actors and experts considered our application helpful, especially as a rehearsal tool to prepare performances before motion capture shoots. They indicated that our application could reduce the time to prepare performances support the preparation of physical acting scenarios.

    Low-cost mixed reality simulator for industrial vehicle environments2016Inngår i: Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Volume 9740, 2016, s. 597-608Konferansepaper (Fagfellevurdert)
    Abstract [en]

    High-end industrial vehicle simulators are generally expensive and aim at providing a high level of realism. The access to such simulators is often a limited resource to researchers and developers who find themselves using a PC-based simulator instead. We challenge this approach by introducing a low-cost mixed reality simulator for industrial vehicles that allows to test new vehicle control concepts and design ideas in a rapid prototyping manner. Our simulator prototype consists of a head-mounted projection display, a CAVE-like room covered with a retro-reflective cloth and a rotatable chair with controls to steer an industrial vehicle. The created digital environment represents an obstacle course for an excavator and can be controlled by a joystick, a keyboard and can be explored by natural head movements. Performed user tests with 21 participants showed that the mixed reality simulator is perceived as more realistic, natural to use and provides a more immersive experience than a PC-based simulator with the same environment and controls.

    The Effect of Field of View on Social Interaction in Mobile Robotic Telepresence Systems2014Inngår i: Proceedings of the 9th ACM/IEEE International Conference on Human-Robot Interaction (HRI 2014), IEEE conference proceedings , 2014, s. 214-215Konferansepaper (Fagfellevurdert)
    Abstract [en]

    One goal of mobile robotic telepresence for social interaction is to design robotic units that are easy to operate for novice users and promote good interaction between people. This paper presents an exploratory study on the effect of camera orientation and field of view on the interaction between a remote and local user. Our findings suggest that limiting the width of the field of view can lead to better interaction quality as it encourages remote users to orient the robot towards local users.

    Semi-Autonomous Cooperative Driving for Mobile Robotic Telepresence Systems2014Inngår i: Proceedings of the 9th ACM/IEEE International Conference on Human-Robot Interaction (HRI 2014), IEEE conference proceedings , 2014, s. 104-104Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Mobile robotic telepresence (MRP) has been introduced to allow communication from remote locations. Modern MRP systems offer rich capabilities for human-human interactions. However, simply driving a telepresence robot can become a burden especially for novice users, leaving no room for interaction at all. In this video we introduce a project which aims to incorporate advanced robotic algorithms into manned telepresence robots in a natural way to allow human-robot cooperation for safe driving. It also shows a very first implementation of cooperative driving based on extracting a safe drivable area in real time using the image stream received from the robot.

    Auditory immersion with stereo sound in a mobile robotic telepresence system2015Inngår i: 10th ACM/IEEE International Conference on Human-Robot Interaction, 2015, Association for Computing Machinery (ACM) , 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Auditory immersion plays a significant role in generating a good feeling of presence for users driving a telepresence robot. In this paper, one of the key characteristics of auditory immersion - sound source localization (SSL) - is studied from the perspective of those who operate telepresence robots from remote locations. A prototype which is capable of delivering soundscape to the user through Interaural Time Difference (ITD) and Interaural Level Difference (ILD) using the ORTF stereo recording technique was developed. The prototype was evaluated in an experiment and the results suggest that the developed method is sufficient for sound source localization tasks.

    Measuring the quality of interaction in mobile robotic telepresence systems using presence, spatial formations  and sociometry2013Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    A mobile robotic telepresence (MRP) system is characterized by a video conferencing system which is mounted on a mobile robotic base. The system allows remote pilot users to move the robot around while communicating with local users situated in the robot’s environment. One of the most promising application areas for MRP systems is to deploy them in homes of elderly who are in frequent contact with health care professionals and/or alarm operators. Using MRP systems, elderly can get in immediate contact with these services even without leaving their homes. However, this poses some challenges for the health care professionals and alarm operators. The alarm operators traditionally communicate with their clients using the telephone while the health care professionals see their patients face-to-face with little interference of computer applications. The encounters between health care professionals and patients typically take place at clinics. Neither the health care professionals nor the alarm operators visit the elderly in person. Accordingly, they have no knowledge about the layout of the homes or where the elderly may reside. Thus, the social communication between them and the elderly via MRP systems is more complex than their traditional interaction with elderly.

    This compilation thesis makes a contribution towards understanding how interaction is affected by MRP system embodiment. The work focuses on measuring quality of interaction in MRP systems deployed in domestic settings in elder care. The thesis proposes a set of useful tools for measuring interaction quality. These tools are presence, spatial formations and sociometry. They were selected based on their ability to capture important characteristics for communication via MRP systems, e.g. social communication and mobility, and have been evaluated in experiments with real end-users, that is with alarm operators, health care professionals and elderly. The tools used to conduct the experimental evaluations of MRP systems include video-based evaluations, driving sessions and retrospective interviews. These methods were carefully chosen and take into consideration the organizational background of the participants involved and the challenge of conducting experiments with the aforementioned groups of users.

    Measuring the quality of interaction in mobile robotic telepresence: a pilot's perspective2013Inngår i: International Journal of Social Robotics, ISSN 1875-4791, E-ISSN 1875-4805, Vol. 5, nr 1, s. 89-101Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article presents a method for measuring the quality of interaction in social mobile robotic telepresence. The methodology is in part based on Adam Kendon's theory of F-formations. The theory is based on observations of how bodies naturally orient themselves during interaction between people in real life settings. In addition, two presence questionnaires (Temple Presence Inventory and Networked Minds Social Presence Inventory), designed to measure the users' perceptions of others and the environment when experienced through a communication medium are used. The perceived presence and ease of use are correlated to the spatial formations between the robot and an actor. The proposed methodology is validated experimentally on a dataset consisting of interactions between an elder (actor) and 21 different users being trained in piloting a mobile robotic telepresence unit. The evaluation has shown that these tools are suitable for evaluating mobile robotic telepresence and also that correlations between the tools used exist. Further, these results give iportant quidlines on how to improve the interface in order to increase the quality of interaction.

    The Craft of Programming Interaction2012Inngår i: Proceedings of International Workshop on the Interplay between User Experience Evaluation and Software Development (I-UxSED 2012) / [ed] Effie Lai-Chong Law, Silvia Abrahão, Arnold P.O.S. Vermeeren, Ebba Thora Hvannberg, 2012, s. 26-30Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The creation of useful artefacts with rich experiential qualities required quality driven interaction designers and programmers with the ability to simultaneous problem setting and problem solving. Interaction design is a design practice that defines the appearance and function of digital artefacts. Bridging interaction design and engineering is problematic because design and engineering have different epistemology. Designers are trained to see a plethora of future designs for a situation and explains the phenomena of a context. Engineering focus on problem solving and depends on agreement about ends. In this paper I suggest that the poor state of designers and programmers who are not standing together can be avoided if we give up the claim that software development should be engineering or science, and instead see it as a quality-driven craftsmanship.

    A Mobile Graph-Like Visual Programming Language2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Visual programming is a programming paradigm commonly used for game scripting, it also has applications in other areas such as for example patcher languages for music and animation and even a few languages for general purpose programming. By using visual programming complex tasks can be made easier by abstracting the code and letting the user express a flow of commands instead. This also gives a better overview of the problem and how the different parts connect. By graphically connecting nodes the program flow will be made clear even for those new to programming. Unfortunately, visual programming is mostly limited to laptops and stationary computer systems. Touch enabled mobile devices which perhaps would be even better suited for a visual programming approach are left with textual programming environments, which doesn’t use the capabilities of the touch screen, and a few non-graph-like visual programming languages, which use interlocked blocks to represent code. To explore how well graph-like visual programming would work on mobile devices a study will be conducted in which a lo-fi design is created and iteratively evaluated and improved using a modified NEVO process. The design will be created and improved based on existing visual programming interfaces and research in the area of visual programming, interaction design and information design, combined with the input from the test subjects. In this work a mobile, visual, graph-like, general purpose programming language has been designed. A lo-fi prototype of the language has been created to display how the language would look on a mobile system if realized. The lo-fi prototype was then tested with a method given by Rettig to give an indication of the systems usability measured by its task completion time compared to the task completion time of a mobile textual system. There is also a qualitative analysis on the responses from the test users. The tests were conducted both on people new to programming as well as people who have been programming for a while.

    Conspicuity index: Looking for a possible objective measurement of visibility taking context into account2008Inngår i: Proceedings of the 40th Annual Conference of the Nordic Ergonomic Society, 2008Konferansepaper (Fagfellevurdert)
    Abstract [en]

    An emergency exit sign can be more or less visible. Something has to do with the sign itself: with bright colors it might be more visible than with faint colors. But also the context plays a role: alone on a white wall it will most likely become more visible than on a wall full of brightly colored posters. There is also a subjective side to the matter; you will more likely see the sign in an emergency situation than in an everyday situation. In the field of Information Design there is a need for an objective and easily administered measurement of conspicuity. Today a time measurement using visual search is possible, but often difficult and unpractical to use in real life.

    In a small pilot study I have tested a new method of conspicuity index, a measurement method where the subject starts by looking at the target whose conspicuity is to be measured, then gradually looks away while attending to the target in the corner of his or her eyes until detection no longer is possible. The angle where detection ends is the conspicuity angle. Previous studies show a high correlation between the conspicuity index and traditional search time measurements. Results from this study show good accordance with intuitive impression of saliency.

    Nautiskt 3D-GIS med sikte på kognitiv avlastning2007Inngår i: Kart og Plan, ISSN 0047-3278, Vol. 67, nr 3, s. 183-191Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A 3-D Nautical GIS is suggested in this paper. The system is aimed at nautical navigation and simplifies navigation by adding three major features to existing chart systems: The egocentric view, by allowing the geographical data to be viewed from an bridge perspective the problem of mental rotations is removed; the seaways, displaying traffic separated fairways and individual track lines and the NoGo area polygons displaying warning areas for waters too shallow for the individual ship in the current tidal situation.

    Abstract [en]

    In this work-in-progress we present some ideas and findings involving map design and human performance. Satellites has once and for all automated geographic positioning and resulted in a plethora of map applications, not only in professional transportation but also in the private sphere, in cars and even for street use in mobile phones. But many people have problems using the traditional bird's-eye view maps. The maze experiment presented here show that an egocentric ("out of the window") view of the map results in faster decision making and fewer errors. Can this also address some of the human-out-of-the-loop problems of navigation automation?

    Arduino in Museum Exhibition: Lessons Learned When Working With Design Students Inexperienced in Coding2015Inngår i: Proceedings of the Ninth International Conference on Tangible, Embedded, and Embodied Interaction, 2015, s. 715-720Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This work-in-progress paper describes the lessons learned when introducing Arduino and Processing programming into a museum exhibition design course. 20 information design students from Sweden, with no previous knowledge in programming, participated in the course. The students' task was to create five interactive exhibition stations at a museum in five weeks. As an experiment, Arduino and Processing programming was introduced into the course in 2014. The ambition with the experiment was to enlarge the information design students' repertoire and find ways to develop the interactive aspects of the exhibition medium. The aim of the paper is to identify and discuss challenges and strengths when introducing code as design material in information design education. The findings presented are based on the students' reflection stories. This work is in progress and we aim in the future to 1) continue the analysis of the material 2) with the findings develop the information design education further and 3) explore the relation between tangible and intangible experience of interactive museum artifacts from a designer's and a museum visitor's perspective. We consider this to be an important matter with branches into the TEI community. We appreciate any feedback on our work.

    ”Kryddan i maten”: Redesign av en kokbok2009Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The purpose of this project has been to redesign an already existing cook-book. The title of the book (directly translated), “Season in food – the year around with herbs and spices”, contains what the headline imposes: spices, herbs and food. But when the author tries to entwine these parts and communicate it to the reader it is not working all to well due to a poor and inconsistent graphic design.

    I have followed the theories and values of information design when I redesigned the book layout with the intent to simplify the communication between author and reader. In the progress to make a complete dummie of the book I did multiple literature studies, book analysis, tests and a vast number of drafts.

    In this report I will describe the whole process from start to finish. It is impossible to explain every aspect of every theory and still make it interesting to read. Instead I try to explain the processes in a more comprehensive way. But details are inevitable and at those times it helps to use the appendix.

    HCI - En analyserande kartläggning av datavetenskapliga metaforer inom digitalisering2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Vi har utrett möjligheter och begränsningar att använda metaforer i mjukvaruutveckling. Metaforer i vårt arbete syftar till det fysiska koncept som omvandlats till något digitalt. Vi har använt oss av fem olika digitaliseringar för att utreda och analysera deras metaforer. Vårt syfte var att vidga perspektiven för utveckling av innovationer. Det har vi gjort genom att kartlägga metaforer, analyserat dessa och diskuterat med utomstående forskare. Information har vi hämtat från olika forskningsartiklar som berör metaforer, HCI och digitalisering för att kunna koppla samman metaforernas roll inom dessa områden. Vi har även deltagit i konferensen ABB Automation Scandinavia och fått stöd av Susanne Timsjö, Vice president, strategic innovation program PiiA (Process Industrial IT & Automation), SICS Swedish ICT Västerås. Vårt arbete har lett fram till att metaforer innehåller många möjligheter som kan tas tillvara och bör finnas med i utvecklingsprocessen. Det har också visat sig att metaforer möjliggör smartare lösningar.

    Exploring Interaction Design Perspectives on Heavy Vehicles2017Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Interaction design is more crucial than ever as an ingredient in product development and digitalization. Its need is driven by a trend where software based functionality is becoming increasingly important in all types of product features, simultaneously as new technology moves the frontier where interaction between human and computer takes place. There is also a market demanding renewed experiences, more efficient, stimulating and fashionable, which enterprises seek to deliver to attract customers. Also[WM1] , as systems, for example vehicle systems, get increasingly information intense, the information exchange with the user becomes a factor for safe and successful operation, thus increasing the need for a proficient interaction design.

    This research investigates how interaction technologies, interaction design principles, and machine information systems can be used to provide user experiences and efficient interaction between the operator and industrial mobile machines; for example, agricultural machines and construction machines. The research combines software engineering and interaction design together with an industrial perspective. It does so by studies, both in literature and through field studies of operators, by design exploration and prototype realization.

    The thesis describes the design space for heavy vehicles through different perspectives. It outlines the principal dimensions of interaction design and the benefits of including design in product and services realization. It presents perspectives on the challenges for the different stakeholders involved, covering the operator of the machines, the software engineer and the designer. It depicts a method for gaining detailed insights into operator’s daily behavior, with minimal interference with their work. Furthermore, it introduces a tool for practitioners to explore interaction design using mixed reality and free head movements, and it investigates possible interfaces using augmented reality.

    360 Degree Mixed Reality Environment to Evaluate Interaction Design for Industrial Vehicles Including Head-Up and Head-Down Displays2018Inngår i: Lecture Notes in Computer Science , Volume 10910, 2018, s. 377-391Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Designing and testing new information and safety features for industrial vehicles do not need to involve the realization of high-fidelity and expensive simulators. We propose a low-cost mixed reality environment which allows for rapid development and rearrangement of a virtual and physical setup of a simulator for industrial vehicles. Our mixed reality simulator allows for safe testing of controls, information, and safety features to support drivers of industrial vehicles. In this paper, we test the implications of showing extra digital information to excavator drivers through a virtual environment, an external head-up display as well as a head-down display. Through user tests we have seen first indications that projected information through our mixed reality system and content on a head-up display is perceived as more helpful and intuitive than using head-down displays, when controlling our industrial vehicle simulator. Moreover, we have seen that the fear of overseeing an obstacle or other important information is lower when using a head-up display, in comparison to other tested visualization options. © Springer International Publishing AG, part of Springer Nature 2018.
